I was looking into my tank with a red flashlight tonight, when I heard a splash and the unmistakable sound of a fish hitting the floor. After a mad scramble to turn on the room lights and locate the fish, I found my hippo tang laying on the floor behind the tank. I easily scooped him up off the floor through the door in the stand and put him back in the tank. He swam to the bottom and hid in the rock and I think he is OK...won't know for sure until tomorrow. But when I scooped him up off the floor, he stabbed me in the thumb with what I think was his dorsal fin and it hurts like hell from my thumb to my chest. Do tangs have spikes on their dorsal fins?
